Application filed. .anuary 14, 1928, Serial No. 246,885, and in Great Britain January 1 1, 192?.

This invention relates to in'iproven'ients in apparatus for withdrawing measured quantities of liquids or semi-liquids from tanks or other bulk storage receptacles, and dischaining same into cans or other containers; and is designed more especially for viscous liquids, such as syrup, treacle, paint or like liquids or semi-liquids. My apparatus is partici'ilarly suitable for syrup and. treacle,

i which have to be filled at the sugar refinery in exaetly-measured (plantities of a certain weight into cans or tins for retail sale to the public.

lily invention relates to iii'u'nrovements in is n'ieasuring apparatus of the type in which a in'ieasuring receptacle fitted with a piston and having a wall of cyliinlrically curved form, is angularly displaeeable in a correspondingly curved seating or casing having an opening in coimnunieation with a bulk storage receptacle, to bring it from the receiving position in which it is in commi'inication with the bulk storage receptacle to a discharging position, or vice versa.

One of the features ofmy invention to provide a measuring apparatus of the type referred to, rotatable through an angle of 90 degrees or therealmuts, in which the angular displacei'nent of the measuring receptacle is adopted to operate the piston, the arrangement being such that lost motion is provided for in the operative mechanism of the me: s-

urinp; receptacle and its piston, whereby the piston is not operated until the measuring receptacle is in the receiving or discharging position.

Further features of my invention consist in providing the piston with an adjustable stop to limit the outi ard stroke of the piston, and thus enable the amount of material witl'ulrawn from the supply tank to be exactly controlled, and in providing the curved seating in which the n'ieasuring receptacle moves with an edge adapted to act as a scraper for the curved 45 surface of the measuring receptacle when it returns from its discharging position to its receiving position.

Still further objects and features of my invention are to n'iount the measuring receptacle on the supply tank in such a ay that it can easily be dismounted for cleaning or other purposes and further to mount the measuring receptacle in trunnion hearings of such a character as to permit the friction be tween the curved bearing surfaces of the measuring receptacle and its seating to be easily adjusted according to the viscosity of the material being measured.

The invention will be further (:lesicribed with reference to the accompanying drawin gs, in which Figures 1 and 2 are respectively a side elevation and plan view of my measuring-apparatns.

Referring to the drawings, 1 denotes generally the measuring-receptacle, a portion of the wall of which made of cylindricallycurved form as a172, and this ll10218111lDQ-I'OLGP- tacle has a cylindrical bore 3 which forms ii measuring-ehamber in which works a piston 4L and so constitutes a pump. The rear end of the casing of the measuring-receptacle has a bolted-on cover 5 to close the end of the cylinder. An adjiiistable stop, such as an adjusting screw or screws 6, is fitted in the cylinder cover to limit the outward stroke of the piston. By this means the amount of material withdrawn can be controlled to a nicety.

On the side of the bulk storage or supply tank '7 or the like, and surrounding theoutlet opening thereof, is lined a flanged fitting 8 having an opening or passage 9 \vhichcoin cides with the outlet opening in the supply tank and this flanged lit-ting is made with a cylindrically-curved concave surface 10 to form a bearing for the cylindrically curved wall 2 of the measuring receptacle the two surfaces being made a close working lit to exclude air.

The n1easuring-receptaele is mounted on trunnions 1] the arrangement being such'iha t in. the receiving posit/imp when a measured quantity is being wit-lnlrawn. the tapered mouth 3 of the measuring cylinder 3 coincides with the o 'iening 9 in the flanged. litting 8, and the piston is moving into its outermost position. The trunnion bearings are made in two parts 12 and 13 and carried by the flanged seating, and are provided with thimibserews 14- to adjust the f tion of the cinfved surfaces 2 and 10 according to the viscosity of the material being n'ieasured. It will be noted that there is a space 39 left between the trunnions and. the inner face of the trunnion bearing; 12, and by tightening or slackening the thumhscrews 14: the measuring receptaele is moved slightly towards or away from the curved seating to adjust the friction of the said curved surfaces.

The apparatus may be arral'iged to be operated manually or by power. In the construction shown the apparatus is operated by hand, a crank-handle 15 attached to the measuring-receptacle 1 being provided for the purpose of eflecting the angular displacement of the said receptacle through 90 degrees. The piston 4 may be operated by the angular displacement of the measuring receptacle by any suitable means. In the arrangement shown the position has two rods 4 and the outer end of each of these piston rods is pivotally connected at 16 to a lever 17, arranged between them, which lever is in turn pivotally connected by links 18 to a projection 19 on the casing of the measuring receptacle. The lever 17 has an upper extension 17, which when the measuring receptacle is moved to the horizontal or receiving position contacts with a roller stop 20 carried at the outer end of a pair of bracket arms 21, 22, at each side. These bracket arms at their inner ends are secured to the flange fitting 8. A second roller stop 23 is carried by the inner end of the bracket arms 21. The two pairs of bracket arms at their outer ends are connected by a screw bolt 24 and separated by tubular distance-piece 25 thereon. When the measuring-receptacle is swung upwards through 90 degrees or thereabouts from the horizontal or receiving position to the vertical or discharge position, the extension 17 of the lever 17 comes against the upper roller stop 23, and the lever and links assume such a position that the piston is caused to move downwards in the measuring cylinder 3 to discharge the measured quantity.

The connection between the measuring receptacle and the piston by means of the arrangement of levers and links described permits of a certain amount of lost motion, so that the movement of the' measuring receptacle does not begin to operate the piston tacle moving over it.

until the bore of the measuring receptacle begins to register with the supply tank outlet 9 when the receptacle is moved into the receiving position, or to clear the lower edge of the curved seating in the discharge position.

.The mode of operation is as follows In the receiving position shown in- Figure 1, with the piston 4 in its outermost position and in contact with the adjustable stops 6, the cylinder is filled with the measured quantity of liquid. The measuring-receptacle 1 is then rotated by means of the handle 15 through an. angle of degrees or approximately so into its discharging position, in which the measuring-cylinder stands vertically above the can or other container intowhich the liquid is to be delivered, and by this angular movement the opening 9 in the flanged curved seating 8 is closed by the upper part of the curved wall of themeasuring-recep- The piston is then move inward by the action of the lever 17 and the links 18, as already explained, to eject the contents of the measuring-cylinder 3 into the can, after which the measuringreceptacle is swung down again through 90 degrees to its initial position, and during this movement the outward stroke of the pi ton takes place and a fresh charge is drawn into the measuring-cylinder. During this return movement of the measuring receptacle, the sharp bottom edge 27 ot the concave seating wipes oil any liquid adhering to the curved face 2 of the nieasuring-receptacle and also forms a drip-edge. The extension 17* on the lever 17 coming into contact with the stop 20 limits further downward movement of the n1easuring-receptacle.

The apparatus is provided with a counterweight 28 on a lever arm 21) fulcrumed on one of the trunnions to counterbalance the weight and facilitate the working 01? the apparatus.

The mounting of the measuring receptacle in the two-part trunnion hearings on the flanged seating 8 fastened to the supply tank is a very convenient construction, as it enables the measuring receptacle to be easily dismounted for cleaning or other purposes when required. It is only necessary to unscre the thun'ibscrews 14, and the whole measuring receptacle and its operating mechanism can then be lifted 011 to give access to the bearing surfaces and the interior of the receptacle.

It is to be understood that the apparatus need not be directly fixed on the bulk storage tank, as in some cases it may be convenient for it to be used at a distance ax ay from the tank and connected thereto by piping.
